AWNING-ARM.

Specification of Letterslatent. Patented Nov, 24, 1914,

Application filed November 18, 1913. Serial No. 801,622.

To all whom it may concern:

Be it known that I, FREDERICKIA. ANTON, a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Awning-Arms, of which the following is a specification.

This invention relates to laterally foldable awning arms, such, for instance, as are described in Patent No. 986,120 granted to me March 7, 1911. Among the advantages claimed for this class of arms is the fact that the roller and the arms may be secured to the building within a very limited vertical space, thus making them especially adapted for attachment to the transom-bar of the modern store front which has a transomwindow above the show window.

It is the object of my present invention to design the supporting bracket for the awning-arm and the inner end of the arm itself, so that even less vertical space is required for the support of the awning than heretofore; in other words, to provide the awning arm with a bracket that can be secured to the transom-bar immediately back of the rollerinstead of below the roller.

It is a further object to provide a special form for the inner end of the arm which eX- tends out belowthe roller.

It is a further object to provide a special means for adjusting the extension of the arm so that the limit of the extension may be adjusted; that is to say, an adjustable means for preventing the joints of the arms from cominginto a line so as to lock the arm and prevent it from folding as the awning is rolled up.v

It further consists of the parts, improvements, and combinations hereinafter set forth and claimed.

In the drawings accompanying and forming part of this specification and in the de scription of the drawings I have shown my invention in its preferred form and what I deem to be the best mode of applying the principles thereof; but it is to be understood that, within the scope of the appended claims, I contemplate changes in form, proportions, and materials, the transpositionof parts, and the substitution of equivalent members, without departing from the spirit of my invention.

Figure 1 is a side elevation of an awning arm made 1n accordance with the principles of my invention, showmgalso an end new of the roller in proper position, parts of the bars in the arm members bOlIlgIGlllOVGCl. Fig. 2is a view of the locking plate, detached. Fig. 3 is a sectional elevation, on line 3 in Fig. 4, of the pivot bracket, detached, And Fig. 4 is a back view of that bracket. Fig. 5 is a sectional elevation, on line 5 in Fig. 1, of one of the middle hinge members, showing the adjustable stop. Fig. 6 is a sectional elevation, on line 6 in Fig. 1, of the supporting bracket. Fig. 7 is a side elevation of the inner pivot end of the arm. Fig. 8 is a sectional view thereof on the line 8 in Fig. 7. Fig. 9 is a plan view of the arm, complete, with parts of the bars in the arm members removed.

Similar reference characters indicate like or corresponding parts throughout the several views.

The supporting bracket for the arm comprises preferably a single malleable iron casting having a plate 10 whereby it is to be secured to the buildingor the transom bar by means of bolts, lag-serews, or other suitable means, an outwardly extending vertically disposed plate 11, and reinforcing ribs 12.1

13 is the awning roller on which the awning fabric is rolled, and is mounted so as to be immediately in front of the supporting bracket.

14, 14 are two slots extending in an are having a radius from the center of the roller.

15 is the pivot bracket having two lugs 16 and 17, each lug having a hole therethrough, 19, 19, to receive the pivot bolt 22. The pivot bracket is secured to the supporting bracket by means of two bolts 20, 20 which pass through the holes 18, 18 in the pivot bracket and through the slots; also these bolts pass through the holes in the locking plate 21 on the opposite side of the bracket. The lower lug 17 of the pivot bracket is longer than the upper lug so that the pivot bolt is inclined laterally; and the locking plate 21 is thicker at its upper end than at its lower end, to compensate for the similar varying thicknessof the pivot bracket, so that the same length of bolts may be used for each set of holes and slots; and the holes 18, 18

through the pivot bracket are at right angles to the faces of the pivot bracket and the locking plate so that the heads and nuts of the bolts are given a flat hearing so thenuts may be screwed on tight and the bolts kept from becoming loosened,

23 is a malleable iron casting forming the inner end of the awning arm proper. It is formed with the two lugs 24%, 24:, each having a hole 25 for the pivot bolt 22, whereby this member is pivoted to the pivot bracket. It is also formed with an extension 26 which projects outwardly and downwardly from its lower portion so as to clear the roller.

27 and 28 are reinforcing webs. The pivot is set at a lateral angle in one direction as already noted; and the extension 26 is so disposed that the bar 29, which comprises the main length of the inner member of the arm is secured to that extension with a lateral incline in the opposite direction. The pivot is also set at an angle outwardly from the bottom up.

The outer end of the bar 29 is secured to the member 30 of the middle hinge, this member having a reinforcing rib 31 extending around it, and having two lugs 32, 32 which hold a bolt 3% to which the other middle-hinge member 33 is pivoted. T 0 this other middle hinge member is secured the inner end of the bar 36 which forms the main length of the outer member of the awning arm proper, the bar being secured to the extension 35, as shown. The outer end of this bar is secured to a casting 87 which is pivoted at its outer end to a pipe clamp 38, by means of a pivot'bolt 39, the pipe clamp embracing the awning pole 40. It will be understood, however, that this form of awning pole and clamp is illustrative, only, of any suitable pole and means for pivoting the outer end of the awning arm to the pole.

My invention relates to the class of awnings in which the awning is raised by drawing up the fabric on the roller, this being effected by rolling the roller by a crank or any suitable mechanism.

My arms are to be used in pairs, lefts and rights, so that the arms of each pair fold in opposite directions. When the arms are extended, and it is desired to raise the awning, the rolling of the awning on the roller has the eflect of folding the arms, as explained fully in my prior patent. WVhen the awning is to be lowered, this is effected by unrolling the fabric in the usual manner, the inclines of the arm members and pivots causing, by the force of gravity, the extension of the arms and fabric. Now, if the arms were permitted to be so fully extended as to bring the three pivots in a straight line or beyond the straight line, the arms would become locked and would not start to fold on again rolling up the awning. In order to prevent the three pivots from coming into a straight line, I provide a set-screw 4L2 threaded through a boss 41 in the firstnamed member of the middle hinge and lo cated in the extension of the said member beyond the pivot bolt, the set-screw being so located that the other member of the middle hinge strikes against its head; and the screw is so adjusted that the stop occurs before the three pivots come into the straight line. I also provide a lock-nut 4-3 to hold the adjusting screw in any position to which it may be adjusted. This adjusting screw may be set in proper position during the process of manufacture, or when setting up the arm; it may also be adjusted afterward to compensate for the wear of the parts, especially the wear of the pivots. It is also to be noted that by connecting the pivot bracket with the supporting bracket in the manner described, the dip of the arm. may be adjusted by raising or lowering the former on the latter bracket. Yet this-shifting of the pivot bracket does not change its relation with the center of the roller; on the other hand, in any position, there is ample clearance between the roller and the brackets for the accommodation of the fabric rolled upon the roller. It is also to be noted that the supporting "bracket is quite narrow from front to back, and also that by projecting the pivot bracket laterally from the side face of the supporting bracket, no extra space is required between the roller and the transom-bar for accommodating thepivot bracket. And the supporting bracket need be only wide enough from front to back to accommodate the pivot bracket. This arrangement permits mounting the roller i1nmediately in front of these brackets without unduly projecting the roller from the building; while the arm proper extends out below the roller and is folded up below it.

What I claim is:

1. The combination of a bracket comprising two plates set at right angles to each other, one of said plates having two slots in the same are; a pivot bracket having two lugs, a pivot bolt extending through said two lugs and disposed at a lateral angle; a locking plate; said pivot bracket and said locking plate having bolt holes registeringwith the respective slots; two bolts extending through the respective bolt-holes and slots and clamping the plate and pivot bracket on opposite sides of said slotted plate; an awning arm proper comprising two laterally foldable members, the inner end of the inner member being pivoted on 3 said pivot bolt and the outer end of the outer member being pivoted to an awning pole; and an adjustable stop on said arm members to prevent the three pivots from coming into line with each other and locking the arm in extended position.

2. j The combination of a supporting bracket having a plate adapted to be secured to a transom-bar or other suitable support and having a plate extending outwardly in a vertical plane substantially at right angles to the first-named plate; a pivot bracket ex tending laterally from the side of the second-named plate; means for adjustably securing the pivot bracket to the supporting bracket; and an awning arm adapted to be pivoted on said pivot bolt, and extending outwardlv from the bottom of said pivot bracket.

3. The combination of a supporting bracket adapted to be secured to a transombar or other part of a structure and having a vertically disposed face extending out substantially at right angles to said transombar or other part; and a pivot bracket adjustably secured to said face and extending laterally therefrom.

4. The combination of a supporting bracket adapted to be secured to a transombar or other part of'a structure and having a vertically disposed face extending out substantially at right angles to said transombar or other part and having slots disposed in the same are; a pivot bracket; a locking plate; and two bolts, said pivot bracket being secured to said face and extending laterally therefrom and said locking plate being on the side of the supporting bracket opposite said face, and said bolts securing said parts together and extending through said slots.

5. The combination with an awning roller and a laterally foldable awning arm, of a supporting bracket adapted to be secured to a structure immediately back of the roller, a pivot bracket secured to the supporting bracket, and said awning arm being pivoted to said pivot bracket immediately back of the awning roller and extending, thence downwardly and outwardly under said roller.

In testimony whereof I have aflixed my signature in presence of two Witnesses.
